Overview: Very Early signs of Pregnancy Week 1 to Week 6
Weeks 1-2 Pregnancy Symptoms
Week 1 of pregnancy is usually your menstrual days. Although you are not technically pregnant in the first two weeks of pregnancy, healthcare experts calculate pregnancy from the first day of last periods to estimate the gestational age accurately.
Ovulation happens around the 14th day of the menstrual cycle. And if you have unprotected intercourse around the time of ovulation, there are high chances for the egg to be fertilized by the sperm leading to pregnancy.

No visible symptoms yet: There will be no symptoms of pregnancy yet. Pregnancy symptoms usually start to develop after implantation.
Fertilization occurs: The released egg is viable for up to 24 hours after ovulation and sperm can live up to 5 days in a female reproductive system. So if you have had unprotected intercourse around the time of ovulation, the sperm is likely to fertilise the egg around the time of ovulation.
Weeks 3-4 Pregnancy Symptoms
Once the egg is released from the ovary, it travels to the fallopian tube and waits for the sperm to fertilise it. The fertilised egg travels back to the uterus and attaches itself to the uterine wall after around 6 days of fertilization leading to pregnancy.

Hormonal changes begin: After ovulation, if the egg is fertilized by the sperm, several hormone changes occur in the body including elevated levels of estrogen and progesterone. The HCG(Human chorionic gonadotropin) levels in the body start to rise.
Breast changes start: Changes in the breast including changes in breast size, sensitive nipple area, darkening of the region around the nipple can occur from as early as 1 to 2 weeks of implantation.
Mild cramping possible: During implantation, there are chances for the pregnant mother to experience abdominal cramps varying from period-like cramps to mild abdominal discomfort.
Early fatigue sets in: Fatigue or unusual tiredness usually starts from around the 1st week of conception. It is usually caused due to hormonal changes, especially progesterone levels.
Weeks 5-6 Pregnancy Symptoms
At around 5 to 6 weeks of pregnancy, you are more likely to experience a missed period followed by a few other pregnancy symptoms including a missed period and morning sickness.

Spotting: Spotting or light bleeding is a common pregnancy sign that some pregnant mothers misinterpret as periods. This bleeding can be caused due to various factors including implantation and hormonal changes.
Morning sickness and nausea: Morning sickness and nausea are the other two common pregnancy symptoms that most pregnant women experience. Although it is called morning sickness, it can happen at any time and not just in the morning.
Breast tenderness and enlargement: Swollen, tender and enlarged breasts is another usual pregnancy sign.
Unusual fatigue and tiredness: Fatigue and tiredness is a common concern for pregnant mothers especially during early pregnancy.
Frequent urination, especially at night: Even before a missed period, most pregnant mothers experience frequent urination especially at night.
Food cravings or aversions: Food cravings and aversions can also develop even before a missed period that is around the third week of menstrual cycle. Craving for a specific food and disliking foods that you used to enjoy otherwise is a common pregnancy sign.
Metallic taste in mouth: A weird metallic taste in mouth that is usually difficult to explain is yet another common pregnancy sign that can occur even before a missed period.
Understanding 1-3 Weeks Pregnancy Symptoms: Changes in the Mother’s Body

During weeks 1 to 3 of pregnancy, the mother-to-be undergoes important changes as her body prepares for conception and potential implantation.
While physical signs may not be prominent at this stage, internal adjustments occur.
The ovaries start maturing and releasing eggs, while the uterus begins thickening its lining in anticipation of a fertilized egg implanting.
Hormonal shifts, including fluctuations in estrogen and progesterone, create an optimal environment for conception.
Changes in cervical mucus occur, becoming thinner and slippery to facilitate sperm movement. Menstruation ceases as pregnancy begins, and although symptoms are minimal, some women may experience light spotting or breast tenderness.
Apart from symptoms, there are a few physical changes the pregnant mother experiences during early pregnancy include:
Backache and lower back pain: Backache or lower back pain is a common occurrence during pregnancy. It can be a dull back ache or a sharp pain or a mild discomfort in the lower back. It is mainly caused by the hormonal changes that occur during pregnancy.
Mild cramping or discomfort: Abdomen cramps and discomfort are common in early pregnancy. It can feel like a period cramp or a mild discomfort in the abdomen region typically caused due hormonal changes.
Increased vaginal discharge: Pregnant mothers often experienced increased vaginal discharge than usual during early pregnancy. This discharge is called “leukorrhea” and it is mainly caused due to excess production of the estrogen hormone.
Heightened sense of smell: Heightened sense of smell is also a common occurrence in pregnancy. And it is caused by the changes in hormones, especially the estrogen hormone.
Mood swings and emotional changes: Experiencing mood swings and roller coaster of emotions during early pregnancy is yet another common symptom that most pregnant mothers experience.
Constipation and bloating: Excess amount of progesterone hormone in the body can slow down bowel movement leading to constipation and bloating even before a missed period.
What does the baby look like in weeks 1 to 3?
After conception, the zygote, or fertilized egg, is now starting its journey toward the uterus in preparation for prospective implantation.
It divides into numerous cells, resulting in the formation of a cell clump known as a blastocyst.
The trophoblast, the outer layer of the blastocyst, will eventually develop into the placenta, and the inner cell mass, which will become the embryo, makes up the blastocyst.
Even though the baby’s physical features and structures have not yet developed, the genetic makeup of both parents comes together to create the baby’s distinctive attributes, such as sex, eye color, and other traits.

By the conclusion of this early stage, the zygote will have successfully implanted into the uterine lining, starting additional growth and embryonic development. The zygote is still developing.
It’s vital to remember that the baby’s development is at its earliest and most basic stage from weeks one to three.
In the following weeks and during the pregnancy, the process of organ formation and the development of distinguishable traits begins.
Top 8 Pregnancy Symptoms: Very Early signs of Pregnancy Week 1 to Week 6
You might not notice any early signs of pregnancy symptoms during the first three weeks of your pregnancy.
In fact, some women might not even be aware of their pregnancy at this point.
However, the following are some potential early warning signs and symptoms that some women may encounter:

1. Spotting
During implantation, which normally takes place between six and twelve days following conception, you can experience mild spotting or a faint pink or brown discharge.2. Changes in breasts
Your breasts could feel sensitive or sore, or they could look fuller or heavier. The color of the nipples might deepen.3. Fatigue
In the early stages of pregnancy, it’s normal to feel more exhausted than usual. Fatigue may be influenced by hormonal changes and an increase in blood output.4. Increased urination
You might discover that you urinate more often than usual. Hormonal changes and increased blood flow to the kidneys are to blame for this.5. Mood swings
One of the crucial early signs of pregnancy symptoms is this. Your emotions and mood might be impacted by hormonal changes.
Mood swings, impatience, or heightened emotional sensitivity could occur.
6. Food cravings or aversions
You can start to crave particular meals or feel strongly repulsed by tastes or scents that you used to like.7. Morning sickness or nausea
Although morning sickness usually begins around the sixth week of pregnancy, some women may have moderate queasiness or nausea in the first few weeks.
8. Bloating and minor cramps
You might suffer minor abdominal bloating or cramping, just like you do during your period.
It’s important to remember that each woman’s experience of these symptoms will be very different, and some women may not have any symptoms at all in the first few weeks of pregnancy.
If you think you might be pregnant, wondering about the early signs of pregnancy symptoms, or have doubts about a home pregnancy test, talk to a fetal medicine expert to confirm your suspicions and take advice.
Chances of Miscarriage
A rather high chance of miscarriage exists during the first three weeks of pregnancy.
An estimated 50 to 75 percent of first-trimester pregnancies result in miscarriage, with the majority happening within the first 12 weeks.
Research has pointed out that chromosomal or genetic abnormalities in the developing embryo are frequently the cause of miscarriages.
Typically, these defects arise at random during cell division or fertilization.
Variables like maternal age, general health, and history of previous pregnancies can affect the miscarriage rate.
Miscarriage risk may be increased in older women and people with specific medical disorders.
Consult your healthcare professional for advice on the best medical treatment and support options if you think you may be having a miscarriage or have other concerns.
8 Things you can do for a healthy pregnancy
Several actions can be taken to encourage a healthy pregnancy in the early stages:

1. Prenatal Vitamin
